Description
[0001] This application claims benefit of U.S. Provisional
Application No. 61/264,292, filed Nov. 25, 2009. This application
also claims benefit of priority under 35 U.S.C. .sctn.119 to French
Patent Application No. 0958026, filed Nov. 13, 2009.
[0002] The present disclosure relates to cosmetic compositions in
the form of a deformable solid comprising hollow particles, at
least one modified or unmodified starch and at least one cationic
surfactant, with a particular ratio of at least one starch to at
least one cationic surfactant.
[0003] Numerous hair care products that impart good cosmetic
properties to the hair are known in the art.
[0004] The conventional products for hair care, for example
after-shampoo products or masks, are most often in the form of more
or less viscous creams. These fluid products are difficult to
measure out, for example because they tend to slip away between the
fingers or leak from their packaging, which can be very troublesome
when they come in contact with clothing, for instance when
travelling.
[0005] Adding thickeners or increasing the proportion of oily phase
to conventional products may modify the texture and notably make it
denser. However, this is often to the detriment of the cosmetic
effects of the composition.
[0006] Moreover, the thickest conditioning compositions may often
have the drawback of possibly requiring a lot of rinsing water to
remove the surplus of product on the hair. In many countries where
access to water is restricted, the rinsing time and therefore the
amount required for proper rinsing of the product are key
indicators of the utility qualities of a composition.
[0007] Moreover, hair care compositions, whether or not they are
products requiring rinsing, constitute for the most part
suspensions of crystals of fats. These suspensions do not always
allow the desired raw materials to be incorporated, or incorporated
in the desired proportion, which may lead to destabilization
effects.
[0008] Finally, users are forever looking for new textures and new
types of products.
[0009] Thus, there is a need for hair care compositions that do not
flow and that are denser, that require little water for rinsing and
that make it possible to avoid phenomena of aggregation of crystals
and therefore flocculation. The required compositions must be easy
to apply on the hair, and they must be very light and very
smooth.
[0010] The present disclosure therefore relates to compositions
comprising a combination of hollow particles, at least one starch
and at least one cationic surfactant, with a particular ratio of at
least one starch to at least one cationic surfactant, which may
make it possible to solve at least one of the problems of the prior
art.
[0011] Thus, one aspect of the present disclosure relates to a
cosmetic composition comprising, in a cosmetically acceptable
medium, at least one type of hollow particle, at least one starch
chosen from modified and unmodified starches, and at least one
cationic surfactant, wherein the weight ratio of the at least one
cationic surfactant to the at least one starch has a value greater
than or equal to 0.3, and wherein the cosmetic composition is in
the form of a deformable solid.
[0012] As used herein, "cosmetic composition in the form of a
deformable solid" is understood to mean a composition that is in a
solid, dry, malleable form, resembling marshmallow (see, for
example, U.S. Pat. No. 3,682,659 for the consistency of
marshmallow).
[0013] The specific gravity of the composition according to the
present disclosure ranges from 0.2 to 0.6, such as ranges from 0.4
to 0.5.
[0014] The compositions according to the present disclosure may
help prevent the risk of it leaking from its packaging, notably
during transport. Moreover, the compositions disclosed herein are
very easy to take hold of, do not flow away between the fingers,
and can be much easier to measure out than the liquid
compositions.
[0015] The compositions according to the present disclosure may
also exhibit good properties of melting or disintegrating during
the application. The hair is supple at the time of application. The
compositions disclosed herein may also lead to properties of
suppleness of the hair on rinsing, of disentangling and of
suppleness on wet hair, and of smoothing on dry hair. Moreover, the
compositions disclosed herein may exhibit good disintegration and
result in a smooth texture after being converted to a cream in the
hand.
[0016] The compositions according to the present disclosure may
also exhibit excellent comfort during application. For example, the
compositions are capable of not running at all, in contrast to
conventional compositions, where there is a risk of irritation,
notably of the face and eyes. The absence of running is greatly
appreciated in the case of perms and dyes, as well as for shampoos
intended for children.
[0017] According to the present disclosure, the compositions can be
in the form of deformable solids that are capable of not staining
and resemble marshmallows. These solids can be modelled, for
example like modelling clay for children. They can be easily broken
by hand so as to take only the required amount of product. For
instance, these compositions can be packaged in monodose form, for
example in the form of small cubes or pieces. From a
bacteriological standpoint, packaging in monodose form is
beneficial because the product is consumed completely in a single
application and there is no remaining product that could be
contaminated after contact with the hands and/or the surrounding
air. This means that it is possible to use less concentrated
preservative systems.
[0018] The hollow particles may allow the compositions of the
present disclosure to have a homogeneous structure (deformable
solid) comprising constituents that normally lead to separate
phases (immiscible constituents, for example oil and water).
[0019] In at least one embodiment of the present disclosure, the
hollow particles are chosen from glass particles, particles of
thermoplastic materials chosen from polyamides such as nylon,
polymers and copolymers of acrylonitrile, particles of vinylidene
chloride, particles of vinyl chloride, particles of acrylic
monomer, particles of styrene monomer, all optionally expanded,
microporous microspheres and silica microparticles.
[0020] The acrylic monomer is, in at least one embodiment, chosen
from methyl acrylate, ethyl acrylate and methacrylate. The styrene
monomer is for example chosen from .alpha.-methylstyrene and
styrene.
[0021] Suitable glass particles according to the present disclosure
include for example, the hollow glass beads sold by the company 3M
under the reference SCOTCHLITE GLASS BUBBLES S 22. 95% of these
beads have a diameter below 74 .mu.m.
[0022] According to at least one embodiment of the present
disclosure, the hollow particles are deformable hollow particles of
an expanded copolymer of vinylidene chloride and acrylonitrile, or
of vinylidene chloride, acrylonitrile and (meth)acrylate or styrene
monomer. It is possible for example to use a polymer containing
0-60% of units derived from vinylidene chloride, 20-90% of units
derived from acrylonitrile and 0-50% of units derived from an
acrylic or styrene monomer, the sum of the percentages (by weight)
being equal to 100%, wherein the acrylic monomer can be chosen from
methyl, ethyl and (meth)acrylate. The styrene monomer can be chosen
from styrene and .alpha.-methylstyrene.
[0023] In another embodiment of the present disclosure, the hollow
particles are hollow particles of an expanded copolymer of
vinylidene chloride and acrylonitrile or of vinylidene chloride,
acrylonitrile and methyl methacrylate. These particles can be dry
or hydrated.
[0024] In yet another embodiment, the hollow particles are, for
example, chosen from microspheres of expanded terpolymer of
vinylidene chloride, acrylonitrile and methyl methacrylate, sold
under the brand name EXPANCEL by the company Nobel Casco, such as
under the references 551 DE 12 (granulometry D(0.5) of about 12
.mu.m and density of about 40 kg/m.sup.3), 551 DE 20 (granulometry
D(0.5) of about 15 to 25 .mu.m and density of about 60 kg/m.sup.3),
551 DE 50 (granulometry D(0.5) of about 40 .mu.m), 461 DE 50 and
642 WE 50 of 50 .mu.m with granulometry of about D(0.5), 551 DE 80
(granulometry D(0.5) from about 50 to 80 .mu.m). It is also
possible to use hollow particles of this same expanded terpolymer,
having a granulometry D(0.5) of about 18 .mu.m and a density of
about 60 to 80 kg/m.sup.3 (EXPANCEL EL23) or with a granulometry
D(0.5) of about 34 .mu.m and density of about 20 kg/m.sup.3. Other
suitable examples include, but are not limited to the particles

and density of about 42 kg/m.sup.3), 551 DE 80 d42 (granulometry
D(0.5) of about 50 to 80 .mu.m and density of about 42 kg/m.sup.3),
461 DE 20 d70 (granulometry D(0.5) of about 15 to 25 .mu.m and
density of about 70 kg/m.sup.3), 461 DE 40 d25 (granulometry D(0.5)
of about 35 to 55 .mu.m and density of about 25 kg/m.sup.3), 461 DE
40 d60 (granulometry D(0.5) of about 20 to 40 .mu.m and density of
about 60 kg/m.sup.3), 461 DET 40 d25 (granulometry D(0.5) of about
35 to 55 .mu.m and density of about 25 kg/m.sup.3), 051 DE 40 d60
(granulometry D(0.5) of about 20 to 40 .mu.m and density of about
60 kg/m.sup.3), 091 DE 40 d30 (granulometry D(0.5) of about 35 to
55 .mu.m and density of about 30 kg/m.sup.3), 091 DE 80 d30
(granulometry D(0.5) of about 60 to 90 .mu.m and density of about
30 kg/m.sup.3). It is also possible to use hollow particles of
unexpanded polymer of vinylidene chloride and acrylonitrile or of
vinylidene chloride, acrylonitrile and methyl methacrylate such as
those sold under the brand name EXPANCEL with the reference 551 DU
10 (granulometry D(0.5) of about 10 .mu.m) or 461 DU 15
(granulometry D(0.5) of about 15 .mu.m).
[0025] Non-limiting mention may also be made of microporous
microspheres sold by Dow Corning under the designation "POLYTRAP"
which are formed from lauryl methacrylate/ethylene glycol
dimethacrylate copolymers; or those sold by Seppic under the
designation "MICROPEARL".
[0026] Suitable silica microparticles according to the present
disclosure, include, but are not limited to hollow silica
microparticles such as those sold by Miyoshi Kasei under the
designation "SILICA BEADS S700".
[0027] Other examples of hollow polymer particles that may be used
in the compositions of the present disclosure include polymers and
copolymers obtained from itaconic, citraconic, maleic, fumaric
esters or acids, from vinyl acetate or lactate.
[0028] In at least one embodiment, the density of the hollow
particles according to the present disclosure ranges from 15 to 200
kg/m.sup.3, for example, ranges from 20 to 120 kg/m.sup.3, such as
ranges from 30 to 80 kg/m.sup.3.
[0029] The hollow particles present in the compositions according
to the present disclosure generally have a mean granulometry D(0.5)
ranging from 1 .mu.m to 300 .mu.m, for example ranging from 5 .mu.m
to 200 .mu.m, such as ranging from 10 .mu.m to 100 .mu.m, for
instance ranging from 15 .mu.m to 50 .mu.m.
[0030] The hollow particles present in the compositions according
to at least one embodiment are filled with at least one gas chosen
from air, nitrogen, isobutane and isopentane.
[0031] The hollow particles in at least one embodiment of the
present disclosure are chosen from microspheres of expanded
terpolymer of vinylidene chloride, acrylonitrile and methyl
methacrylate.
[0032] The hollow particles can be present in the compositions
disclosed herein in an amount ranging from 0.01 to 15 weight. %,
such as ranging from 1 to 10 weight. %, relative to the total
weight of the composition.
[0033] The compositions according to the present disclosure
comprise at least one starch chosen from modified and unmodified
starches. For example, the at least one starch chosen from modified
and unmodified starches can be chosen from macromolecules in the
form of polymers constituted of elementary units that are
anhydroglucose units. The number of these units and their assembly
make it possible to distinguish between amylose (linear polymer)
and amylopectin (branched polymer). The relative proportions of
amylose and amylopectin, as well as their degree of polymerization,
vary depending on the vegetable origin of the starches.
[0034] The at least one starch can, for example, be obtained from a
vegetable source such as cereals, tubers, roots, vegetables and
fruits. Thus, the at least one starch can be obtained from a
vegetable source chosen from maize, peas, potato, sweet potato,
banana, barley, wheat, rice, oat, sago, tapioca and sorghum.
According to at least one embodiment, the at least one starch is
obtained from potato.
[0035] The hydrolysates of the at least one starch can also be
used.
[0036] The at least one starch can be, for example in the form of a
white powder, insoluble in cold water, with the elementary
particles ranging in size from 3 to 100 microns.
[0037] The at least one starch used in the compositions disclosed
herein can be modified chemically by at least one of the following
reactions: pregelatinization, oxidation, crosslinking,
esterification, and thermal treatments.
[0038] According to at least one embodiment of the present
disclosure, these reactions can be carried out as follows:
[0039] pregelatinization by making the starch grains burst (for
example drying and cooking in a drying drum);
[0040] oxidation by strong oxidizing agents leading to introduction
of carboxyl groups in the starch molecule and to depolymerization
of the starch molecule (for example by treating an aqueous solution
of starch with sodium hypochlorite);
[0041] crosslinking by functional agents capable of reacting with
the hydroxyl groups of the starch molecules which will thus be
joined together (for example with glyceryl and/or phosphate
groups);
[0042] esterification in an alkaline medium for grafting functional
groups, for instance C.sub.1-C.sub.6 acyl (acetyl), C.sub.1-C.sub.6
hydroxyalkyl (hydroxyethyl, hydroxypropyl), carboxyalkyl (for
instance carboxymethyl), octenylsuccinic. According to at least one
embodiment, the at least one starch is modified with carboxymethyl
sodium.
[0043] Other suitable examples of the at least one starch include
monostarch phosphates (of the type Am--O--PO--(OX)2), distarch
phosphates (of the type Am--O--PO--(OX)--O--Am), tristarch
phosphates (of the type Am--O--PO--(O--Am)2), and mixtures thereof,
which are obtained by crosslinking with phosphorus-containing
compounds; wherein X is chosen from alkali metals (for example
sodium or potassium), alkaline-earth metals (for example calcium,
magnesium), salts of ammonia, and salts of amines such as those of
monoethanolamine, diethanolamine, triethanolamine, and
amino-3-propanediol-1,2, ammonium salts derived from basic amino
acids such as lysine, arginine, sarcosine, ornithine, and
citrulline.
[0044] The phosphorus-containing compounds can be chosen from, for
example sodium tripolyphosphate, sodium orthophosphate, phosphorus
oxychloride and sodium trimetaphosphate.
[0045] In at least one embodiment, distarch phosphates chosen from
hydroxypropylated starches, are used in the compositions disclosed
herein, such as the product offered under the references PREJEL
VA-70-T AGGL (gelatinized hydroxypropylated manioc distarch
phosphate) or PREJEL TK1 (gelatinized manioc distarch phosphate) or
PREJEL 200 (gelatinized acetylated manioc distarch phosphate) by
the company AVEBE or STRUCTURE ZEA from NATIONAL STARCH
(gelatinized hydroxypropylated maize distarch phosphate).
[0046] When the starches are modified chemically by an
esterification reaction, it is possible to obtain
carboxyalkylstarches.
[0047] In at least one embodiment of the present disclosure, the
carboxyalkylstarches are chosen from carboxyalkyl (C.sub.1-C.sub.4)
starches, such as carboxymethylstarches.
[0048] The salts are for instance alkali metal or alkaline-earth
metal salts such as Na, K 1/2, Li, NH.sub.4, of a quaternary
ammonium or of an organic amine such as mono-, di- or
triethanolamine.
[0049] The carboxyalkylstarches are obtained by grafting
carboxyalkyl groups on at least one alcohol function of starch,
such as by reaction of starch and sodium monochloroacetate in an
alkaline medium.
[0050] The carboxyalkyl groups are, for example, fixed via an ether
function, such as on carbon 1.
[0051] The degree of substitution is for instance from 0.1 to 1,
such as from 0.15 to 0.5. As used herein, the degree of
substitution is understood to mean the average number of hydroxyl
groups substituted with an ester or ether group (in the present
case ether for the carboxymethylstarches) per monosaccharide unit
of the polysaccharide.
[0052] Suitable carboxyalkylstarches according to the present
disclosure comprise units of the following formula:
##STR00001##
[0053] wherein X is chosen from a hydrogen atom, alkali metals, and
alkaline-earth metals such as Na, K 1/2, Li, NH.sub.4, quaternary
ammonium and organic amines. In at least one embodiment, X is an
Na+ ion.
[0054] The carboxyalkylstarches in at least one embodiment of the
present disclosure are non-pregelatinized carboxyalkylstarches.
[0055] In another embodiment of the present disclosure, the
carboxyalkylstarches are chosen from partially and fully
crosslinked carboxyalkylstarches.
[0056] Other suitable carboxyalkylstarches include, but are not
limited to sodium salts of carboxyalkylstarches, for example sodium
salt of potato carboxymethylstarch sold under the designation
PRIMOJEL by the company DMV International. More than 95% of the
particles of this starch have a diameter below 100 microns, such as
below 65 microns.
[0057] According to at least one embodiment of the present
disclosure, it is also possible to use amphoteric starches
comprising at least one anionic group and at least one cationic
group. The anionic and cationic groups can be bound to the same
reactive site of the starch molecule or to different reactive
sites, and in at least one embodiment, they are bound to the same
reactive site. The anionic groups can be chosen from carboxyl,
phosphate and sulphate anionic groups, for example carboxyl. The
cationic groups can be chosen from primary, secondary, tertiary and
quaternary amines.
[0058] Suitable amphoteric starches can be chosen, for example,
from the compounds of the following formulae:
##STR00002##
[0059] wherein
[0060] St-O is a starch molecule,
[0061] Each instance of R is independently chosen from a hydrogen
atom and a methyl radical,
[0062] Each instance of R' is independently chosen from a hydrogen
atom, methyl radicals, and --COOH,
[0063] n is an integer equal to 2 or 3,
[0064] Each instance of M is independently chosen from a hydrogen
atom, alkali metals, alkaline-earth metals such as Na, K, Li,
NH.sub.4, a quaternary ammonium and an organic amine,
[0065] R'' is chosen from a hydrogen atom and C.sub.1-C.sub.18
alkyl radicals.
[0066] Such compounds are described, for instance in U.S. Pat. Nos.
5,455,340 and 4,017,460.
[0067] According to at least one embodiment, the at least one
starch is chosen from compounds of formulae (I) and (II), for
example starches modified with 2-chloroethyl aminodipropionic acid,
wherein R, R', R'' and M are hydrogen atoms and n is 2. For
instance, potato starch modified with 2-chloroethyl
aminodipropionic acid neutralized with soda, marketed under the
reference STRUCTURE SOLANACE by the company NATIONAL STARCH, may be
used in the compositions disclosed herein.
[0068] In at another embodiment of the present disclosure, the at
least one starch is chemically modified.
[0069] The at least one starch present in the compositions
according to the present disclosure are present in an amount
ranging from 0.01 to 15 weight. %, for instance ranging from 0.1 to
10 weight. %, such as ranging from 1 to 10 weight. %, relative to
the total weight of the composition.
[0070] According to the present disclosure, the at least one
cationic surfactant may be chosen, by way of non-limiting example,
from salts of primary, secondary and tertiary fatty amines, all
optionally polyoxyalkylated; quaternary ammonium salts such as
tetraalkylammonium, alkylamidoalkyltrialkylammonium,
trialkylbenzylammonium, trialkylhydroxyalkylammonium,
alkylpyridinium chlorides and alkylpyridinium bromides; imidazoline
derivatives; and cationic amine oxides.
[0071] Non-limiting mention may be made of methyl alkyl
alkylamidoethyl imidazolinium methosulphate (Quaternium-87)
marketed, for instance by the company DEGUSSA under the reference
VARISOFT W 575 PG, or the behenyl trimethyl ammonium chloride
marketed, for example by the company CLARIANT under the reference
GENAMIN KDMP, and cetyl trimethyl ammonium chloride.
[0072] Other suitable examples of the at least one cationic
surfactant include, but are not limited to quaternary ammonium
salts containing at least one ester function such as those of the
following formula (V):
##STR00003## [0073] wherein:
[0074] R.sub.22 is chosen from linear and branched C.sub.1-C.sub.6
alkyl radicals, C.sub.1-C.sub.6 hydroxyalkyl radicals, and

[0284] The texture of composition A was very dry and very friable.
In water, it disintegrated moderately well (clusters remained in
the hands), and resulted in a texture that was not very smooth
after being converted to cream in the hand.
[0285] Composition C was not dry and was not friable. It exhibited
very good disintegration and resulted in a very smooth texture
after being converted to cream in the hand.
[0286] Compositions A and C were applied per half-head on a styling
head, in an amount of 6 g of composition per half-head, then were
rinsed with water.
